To make creation/deletion of resources in different context it's very usefull to use broker module. Where we are publishing to queue "tasks" and consuming them from different threads. In case of working with OpenStack resources we should cache initialized clients and initialized clients can't be shared between threads. So to be able to cache clients each thread has it's own *cache* dict Co-authored-by: Mikhail Dubov <mdubov@mirantis.com> Change-Id: Ic67bd45df375de98140c3fdd20a1af129f0886f0
